I have an NYGBS membership, but that does not mean I can dip into an online database and find the New York records that Julius is looking for. New York is not like Massachusetts where vital records are concerned. There is no one place to look up vital records for the state, and in fact for most of the state there was no formal recordkeeping until circa 1880-1914. For times before that, information comes from the records of individual churches, family bibles, tax records, censuses, newspapers, etc. -- whatever you can find, if anything exists. Some excellent material is free online; there is some good content on familysearch, Ancestry, and AmericanAncestors; NYGBS has some great online resources and (apparently) a lot more exists in the form of paper documents in their archives; and some material is found only in [mostly expensive] published books. I have found that the late decades of the 1700s and the early decades of the 1800s in New York are particularly challenging to research.
